I honestly don't think weight will be an issue. I do 90 curls a night with a 45 lb. dumbbell. With only one arm working, I push to keep it as strong as possible. I agree also with the blade needing to be a thicker steel. I might send your pics to George Lesche and see what he thinks. He might want to buy your design!
no problem send at will.I copied my lesche when i made it..:-) Turning what i have into a functioning design to fit your needs is nothing more than getting a pipe/bar and putting a stop and sliding weight on it.
